APPLICATION OF SDP TECHNIQUE TO SOLVE POWER IN WIRELESS RELAY MIMO

Abstract

The application of optimization techniques to wireless communications, in particular beamforming designs, is an active area of research. The convex optimization methods for the optimal design of MIMO relay models in this paper yield promising results, and open doors to numerous possibilities of extension and improvement to other classes of beamforming problems. This paper focus on the applications of optimization techniques for the design of beamforming schemes in wireless network settings. We have considered the optimal beamforming problems of multiple-input multiple-output (MIMO) relay systems. The mathematical formulations of these problems lead to highly nonconvex optimization problems. The traditional approaches could not solve the problems efficiently especially at large system settings. By applying appropriate optimization algorithms, the proposed method can obtain solutions at near optimality. The contributions of this paper are summarized as follows.
